Monitoring Changes in Delivery Schedules

Use

When you manually create a new delivery schedule or automatically generate one from Electronic Data Interchange (EDI), the system checks the new delivery schedule against the old delivery schedules to ensure that tolerance levels are respected. If the system determines a problem, it issues a message and sets a delivery block.

Features

The system monitors changes of quantity in schedule lines with regard to specified tolerance levels. It checks:

New forecast delivery schedules against old forecast delivery schedules
New JIT delivery schedules against current forecast delivery schedules

A new JIT delivery schedule is checked against the current forecast delivery schedule and not against the old JIT delivery schedule. This is because JIT delivery schedules should follow the forecast delivery schedule as closely as possible.

A schedule line is valid when any of the following apply:

The cumulative released quantity of the new delivery schedule does not exceed (in the case of increasing quantities) or fall below (in the case of decreasing quantities) the cumulative released quantity of the delivery schedule to which it is being compared by more than the tolerance quantity/percent.
The cumulative released quantity of the new delivery schedule is less than or equal to (in the case of increasing quantities) the cumulative released quantity of the delivery schedule to which it is being compared on the schedule line date plus tolerance days.
The cumulative released quantity of the new delivery schedule is greater than or equal to (in the case of decreasing quantities) the cumulative released quantity of the delivery schedule to which it is being compared on the schedule line date minus tolerance days.

If any one of the three checks is successful, the check is considered as a whole successful. The system does not carry out any further checks.

Example

The following example of a new forecast delivery schedule shows how the system carries out these checks:

Tolerance quantity = 90
Tolerance days = 3

Schedule lines	Old cumulative rel. qty.	New cumulative rel. qty.
05/07	1000	1100
05/08	1500	1600
05/09	2000	2000
05/10	2200	2100
05/11	2500	2400
05/12	3000	3000

The quantity is increased on 05/07. Because the deviation (100) exceeds the tolerance quantity (90), the new forecast delivery schedule does not pass the check against tolerance quantity. For this reason, the system also checks the deviation against tolerance days. It determines that the cumulative released quantity in the new forecast delivery schedule (1100) is less than the cumulative released quantity in the forecast delivery schedule from 05/10 (05/07 plus three tolerance days - 2200).The deviation on 05/07 is therefore permitted.

On 05/11, the system determines a decrease in quantity. Because the deviation (100) exceeds the tolerance quantity (90), the new forecast delivery schedule does not pass the check against tolerance quantity. For this reason, the system also checks the deviation against tolerance days. It determines that the cumulative quantity in the new forecast delivery schedule (2400) is greater than the cumulative released quantity in the old forecast delivery schedule on 05/08 (05/11 minus three tolerance days -1500). The deviation on 05/11 is therefore permitted.
